Hierarchical architectures that emulate the function of the lotus leaf are created from multi-scale hierarchical assembled templates directly nanoimprinted on thermoplastic polymers. This hierarchical microsurface and nanosurface topography exhibits a superhydrophobic behavior and self-cleaning properties with static contact angle values up to 160° and contact angle hysteresis below 10°. The superhydrophobic behavior remained more than 1 year after fabrication, which demonstrates the stability of these polymeric self-cleaning topographies.
